Well, I tried everything everyone suggested..such as checking the battery/ground connections and couldn't find anything loose or connected incorrectly. It continued to cut off occasionally until yesterday and it just died on me. the problem is that there is no power going to the amplifier because the power light doesn't even come on. I checked the fuses on both the amp, and near the battery terminal. As far as I know all the wires are connected correctly. So i'm assuming that the amplifier has just had it..lol. I guess I will take it to a sound shop this week.
